1Tetraphenylethylene-BODIPY aggregation-induced emission luminogens for near-infrared polymer light-emitting diodes显示文摘The aggregation-induced emission(AIE) phenomenon provides a new direction for the development of organic light-emitting devices. Here, we present a new class of emitters based on 4,4-difluoro-4-bora-3 a,4 a-diaza-s-indacene(BODIPY), functionalized at different positions with tetraphenylethylene(TPE), which is one of the most famous AIE luminogens. Thanks to this modification, we were able to tune the photoluminescence of the BODIPY moiety from the green to the near-infrared(NIR)spectral range and achieve PL efficiencies of ~50% in the solid state. Remarkably, we observed an enhancement of the AIE and up to ~100% photoluminescence efficiencies by blending the TPE-substituted BODIPY fluorophores with a poly[(9,9-di-noctylfluorene-2,7-diyl)-alt-(benzo[2,1,3]thiadiazol-4,7-diyl)](F8 BT) matrix. By incorporating these blends in organic lightemitting diodes(OLEDs), we obtained electroluminescence peaked in the range 650–700 nm with up to 1.8% external quantum efficiency and ~2 m W/cm2 radiance, a remarkable result for red/NIR emitting and solution-processed OLEDs.Sebnem Baysec Alessandro Minotto Patrick Klein Simone Poddi Andrea Zampetti Sybille Allard Franco Cacialli Ullrich Scherf 2018Science China Chemistry2018,61,8:6

14Prevalence and risk distribution of schistosomiasis among adults in Madagascar:a cross-sectional study显示文摘Background The goal to eliminate the parasitic disease of poverty schistosomiasis as a public health problem is aligned with the 2030 United Nations agenda for sustainable development goals,including universal health coverage(UHC).Current control strategies focus on school-aged children,systematically neglecting adults.We aimed at providing evidence for the need of shifting the paradigm of schistosomiasis control programs from targeted to generalized approaches as key element for both the elimination of schistosomiasis as a public health problem and the promotion of UHC.Methods In a cross-sectional study performed between March 2020 and January 2021 at three primary health care centers in Andina,Tsiroanomandidy and Ankazomborona in Madagascar,we determined prevalence and risk factors for schistosomiasis by a semi-quantitative PCR assay from specimens collected from 1482 adult participants.Univariable and multivariable logistic regression were performed to evaluate odd ratios.Results The highest prevalence of S.mansoni,S.haematobium and co-infection of both species was 59.5%,61.3%and 3.3%,in Andina and Ankazomborona respectively.Higher prevalence was observed among males(52.4%)and main contributors to the family income(68.1%).Not working as a farmer and higher age were found to be protective factors for infection.Conclusions Our findings provide evidence that adults are a high-risk group for schistosomiasis.Our data suggests that,for ensuring basic health as a human right,current public health strategies for schistosomiasis prevention and control need to be re-addressed towards more context specific,holistic and integrated approaches.Sarah Katharina Gruninger Tahinamandranto Rasamoelina Rivo Andry Rakotoarivelo Anjarasoa Ravo Razafindrakoto Zaraniaina Tahiry Rasolojaona Rodson Morin Rakotozafy Patrick Richard Soloniaina Njary Rakotozandrindrainy Pia Rausche Cheick Oumar Doumbia Anna Jaeger Alexandre Zerbo Heidrun von Thien Philipp Klein Govert van Dam Egbert Tannich Norbert Georg Schwarz Eva Lorenz Jürgen May Raphael Rakotozandrindrainy Daniela Fusco 2023Infectious Diseases of Poverty2023,12,2:0
15气候对伊比利亚半岛尼安德特人向现代人人种转变的影响显示文摘伊比利亚半岛对从尼安德特人到现代人的人种转变有着特殊的意义.从东欧向西迁徙的现代人较晚才抵达伊比利亚,因此两个种群之间在这里发生任何可能接触的时间要晚于其他地方.伊比利亚半岛的人种转变发生在海洋同位素第3阶段的早期(约6万到2.7万年前),其间反复强烈的气候变化影响了种群稳定性.本文研究了气候变化和人类相互作用如何影响种群的过渡.结合气候数据与考古遗址数据重建了GI11-10(格陵兰间冰期)和GS10-9/HE4(格陵兰冰期)时期尼安德特人和现代人的生存潜力或生存概率.结果发现,由于气候变化,在GS10-9/HE4期间,伊比利亚半岛的大部分地区已不适合尼安德特人的生存.尼安德特人的定居区收缩为较为孤立的沿海热点.这可能使得尼安德特人的种群结构变得更不稳定,从而引发人口的最终崩溃.现代人大约在GI10期间抵达了伊比利亚,但仅限于半岛最北部地带的局部地区.GS10-9/HE4的寒冷气候阻止了他们的进一步扩张,甚至导致了他们定居区域的缩小.气候变化与人口迁徙使得尼安德特人和现代人两个种群的人口分散在半岛的不同区域.因此,尼安德特人和现代人在广泛的地区共存的可能性不大,而现代人对尼安德特人的最后消亡的影响也有限.Konstantin Klein Gerd-Christian Weniger Patrick Ludwig Christian Stepanek 张旭 Christian Wegener 邵亚平 2023Science Bulletin2023,68,11:0
